New Digital Circuitry with Audio Compression!
All new digital compression circuitry offers lightning fast attack time of 0.5 milliseconds and 5X Sound Amplification. Audio Compression doesn't shut off the audio circuit, it simply reduces the volume to a safe level. This allows you to hear range commands that you otherwise might have missed! The digital circuitry also provides better sound clarity.

Air Flow Control™ Technology
Patented Air Flow Control™ technology delivers superior low-frequency attenuation and performs more consistently across the whole frequency range without increasing the size or weight of the earmuff.

Low Energy Consumption
The Impact™ Sport maintains a battery life up to 350 hours! An automatic 4-hour shut-off feature prevents excessive battery loss in the event the earmuff is not turned off. Operates on 2, AAA batteries (included).
